"Today we welcome Oracle's donation of code that has previously been proprietary to the Apache Software Foundation, it is great to see key user features released in a form that can be included into LibreOffice."

ASF policy is not to incorporate LGPLv3 source as LGPLv3 isn't AL 2.0 compatible ( http://www.apache.org/legal/resolved.html ). The same holds for closed source code; it would need to be under a compatible (ie: liberal) license.

Note that the copyrights belong to individuals on Apache projects too. Any issues for users (the 'corporates') are likely to be around the LGPLv3 licensing; both the copyleft issues and the patent terms.
